IBM DB2 Error Message
-633 the delete rule must be delete rule
Reason for the Error
The code is used to report that the ‘delete rule’specified in a FOREIGN KEY clause of the ALTER TABLE statement is invalid.� The indicated ‘delete rule’ is required because:*�� A self referencing constraint must have a ‘delete rule’ of CASCADE. *�� The relationship would cause the table to be delete connected to the same table through multiple paths and such relationships must have the same ‘delete rule’.
Solution
Change the ‘delete rule’ in the FOREIGN KEY clause.
